3, Panel characteristics: light weight, fireproofing, sound insulation, heat preservation, antiseepage, earthquake resistance, environmental protection, durable, fast, economic. 4, Cost control: the comprehensive cost is lower at least 5% than solid clay brick, but more usable area, the utilization rate has greatly improved.
enclosure (soundproof hood) Use the acoustic enclosure to cover the whole ball mill, and then add a sound absorbing device in the hood to eliminate the reverberation noise. This method usually gains the noise reduction of 2545db (A), but it does not effectively isolate the ball mill transmitting to the outside.
The level of airborne sound insulation relies on the following general principles: flexibility/rigidity. efficiency. mass. isolation. The efficiency of each strategy of insulation can vary with the kind of sound, however in the majority of constructions all the principles of insulation matter. Details of the principles are ...
